Detailing

A GistParameter is used to state the essence, or main point, of a specification.
A good Gist serves two purposes:

• it helps a Planning group to agree on the summary of a specification, Before they spend more time formulating the specification in greater detail.

• it summarizes a detailed specification. This serves several purposes:
. readers can quickly grasp the subject matter
. readers can decide to avoid the detail
. presenters can refer to a specification by using just its tag name and Gist (A reader who needs more detail can ‘drill down’ to the detail using the tag name).
